Love the videos! Question for you: Would it been worth it to backup the chips just in case something were to happen that would damage the nand on installation back on the usb board?
It's a good question. NAND chips are very resilient. And I am yet to see them degrade to a noticeable degree from a little bit of heat. If you look at 13:45 it shows the bitview of NAND content, pay close attention to how solid and undisturbed the vertical lines are at the end of the block. If the live preview of the data looks that clean and solid - then chips are most likely not problematic and will read clean. Putting another heat cycle on them is not going to make more or less damage. This is a 128GB unit, so reading 4 chips and running ECC+ readout can take a full day of work, and amount of clues pointing to the split controller were overwhelming. :)
Sitting at my desk with a kitty in my lap sleeping away, cold glass of milk some cookies and an alert for a new video from my favorite data recovery human. Today is a good day. :-)
Erkin, hi there... not the firts one but always here... very nice job done. Please, make videos about PC 3000 and/or chip off recovery on VNR... detailed ones, everybody will enjoy that... for sure. :) My best wishes... you are the man.
I never get bored watching you work your magic, its fascinating watching someone who truly understands their field getting stuck right in with such confidence. Ty for expanding my understanding of a subject I would never normally have access to.
Good tip for you if you use a lot of Q-tips get the safety Q-tips they have like two and a half times the surface area cleans a lot better I buy them at the Dollar Tree myself
Honestly, I think there are better options. Shapus uses metal clamps, they soak in the heat. Kevlar clamps would be better. I just got another holder today. I will showcase it and share my thoughts on it
@@hddrecoveryservices I'm using the ones made from some kind of blue fiber resin and those really suck up the heat so I need way to much to remove a component I just don't like them much. I wish I had half your intelligence your awesome! (I'm 54)
Terry, the ability to work on these chips is still very undeveloped. We have the unit wired up and NAND was dumped out, but it's a SK Hynix brand TLC chip with ID that we can't pick proper ReadRetry specs. One of the flash tool developers is actively working on a solution that is very effective for Hynix, but registers for the NAND with your ID have not been identified yet. We only have 30-40% of the NAND cleaned of errors so far.
I must apologize if I'm out of place by saying this but, I have been in the I.T. field for 24 years now and I know from experience that any type of DR is a long,tedious and unfortunately sometimes thankless processes. I actually had to send a 2TB HDD in to a DR company and it took them 3.5 years to get the HDD back to me for the customer. Reason being, the machine that it was in got flooded during a hurricane and the client "tried to dry out out" by opening the drive further damaging it. I contacted the client and he had given up on it, but was nearly in tears when I gave him hiss business data back. He now has an on-site and off-site backup system in place now.
TIL chip off is time consuming and last resort. Maybe do a video on the software tools you use like that UFS explorer professional recovery. Is the $60 standard license good enough?
